Hi, I was going through chainsaw project withdrawal and made the mistake of ordering this saw on Facebook marketplace. The pictures looked decent, and I have had decent success with working on 51s and 55s. Missing both front annular buffers? Are they just held in by friction/pressure or is there a screw or bolt involved? l know it's probably simple, but so am I.......... btw, this must be an older model, the cylinder head bolts are not Allen, but instead regular hex headed bolts
